400G CFP2 DCO is a coherent pluggable optical module that complies with the CFP MSA CFP2 hardware specification. It is based on and DP-mQAM modulation, polarization diversity coherent internal detection, and advanced electronic link equalization technology.
On the Host/Client-side, this module can accommodate multiple signal types, including 100GbE, 200GbE, 400GbE, OTUCn (n=[1.. 4]), and OTU4. At the Network Lane Interface, this module supports interfaces of 100G, 200G, 300G, and 400G, with different modulation formats. Multiple 100G clients can be multiplexed onto a single 200G, 300G, or 400G Network Lane Interface. The Network Lane Interface is a duplex LC connector coupled to an optical fiber carrying the DP-mQAM coherent signal in the C-band.
